Featured image

Good day

I have recently started using the Vantage theme. I enjoy the experience of using it so far. The only thing that frustrates me a bit is the featured image size in Blog archive.

My site – http://gasparavicius.com/
Layout of my Blog archive is – Blog.
Featured image size – Large.

Even though the image is large, I can not seem to get it to be as wide as the excerpt text. In my experience with many other themes (while using the same images), this is the default, text is as wide as the featured image.

I really enjoy using Vantage, hope it is possible to solve this issue.

Thank you,

Arvydas
